Stopping and controling animation on start

Question

Whats the best way to stop an animation when you view your scene on start up?
And can adobe 3d support multiple embedded animations and can you control these independently?
At this time I have a simple test file I'm trying to get working with one animation embedded in my imported u3d file. but later on I want to be able to control various animations with different buttons.

You can have multiple animation 3D annotations running at once. You can use javaScript to control some of the some fo the camera parameters. Through the regular UI can save a view of the, e.g., exploded animation, however, the animation may want to have the animation paused to honor the state of that view without the animation continuing. You can control that through the 3D JavaScript API, or the user would have to manually pause the animation, then call the view. The state of the animation can be manually controlled with the animation fader in the toolbar.
There are various examples at the Adobe site's 3D Gallery. Not an animated example, but an example of various views controlled by a JavaScript button:

Maybe a closer example of a single animation controlled by buttons:

There is no reason why multiple annotations, each eith its own animation would not be able to take advantage of the same type of controls. The only limit I know of would be CPU/GPU power.
